IBRICKLAYERS GAUGE.

Application filed September 7, 1923. Serial No. 661,476.

To all whom it may concern:

Be it known that I, BENJAMIN C. Bocos, a citizen of the United States, residing at East Lake, in the county of Jefferson and State of Alabama, have invented new and useful Improvements in Bricklayers Gauges, of which the following is a specification.

ln a device of the above character, the invention aims to provide a construction including spirit levels, height gauges and supporting means therefor to hold the various parts in position in order to moreaccurately construct a wall.

The invention further aims toprovide a construction of device by which the perpendicular-ity and the level of the wall are assured.

A'still further purpose is the provision of means for supporting the bricklayers gauge onthe side of a wall, in combination with means for connecting two similar gauges so as to hold a masons or bricklaye1"s'line horizontally.

The invention comprises further features and combinations of parts to be hereinafter set forth, sho-wn in the drawings and claimed.

In the drawings:

Figure 1 is a view in elevation of a portion of a.wall,.preferably made up of bricks, showing two bricklayers gauges supported thereon and holding a masons or bricklayers gauge line.

Figure 10 is a detail vertical sectional view through the masons line clamp 25.

Figure 11 is a horizontal detail sectional View of the mounting of the set-screw 15 and one of the pointers 20.

Referring to the` drawings, 1 and 2 designate thesupporting plates of the bricklayers gauges. Both gauges are of similar construction and design, in general, with the eX- ception that one is much broader than the other and includes wall gauging rules and means for retaining said rules on the base. The broader of the two gauges includes an additional spirit level to insure leveling the broad gauge Vin a direction with the wall.

The base of each gauge is provided with an outstanding lug 3 between which and a pivoted clamp 4 a spring 5 is interposed for the purpose of cooperating with the clamp to cause the same to bind against a brick for holding the gauge in position. This clamp is pivotally supported between the jaws 6 which stand outwardly from the basev 2. The clamp 4 passes through an opening 7 and secured to the base 2 at a point below the end 8 of the clamp is a lug 9. The lug 9 and the end 8 of the clamp are tapered so as to gouge into ythe mortar between the bricks to hold the base 2 adjacent the outer surface of the wall. V'hen mounting the base in position, the clamp 4 is pressed toward the lug 3, thereby moving the end 8 of the clamp in a direction from the lug 9 and positioning the end 8 so it will engage between the bricks. Vhen pressure upon the lug 3 is relieved, the end 8 of the clamp will bind against the brick and draw the lug 9 against the under surface of the brick. In this way, the base of each gauge is sup-- ported iirmly in position. r

Outstanding from the base is a flange 10 which is provided with a screw projection 11. A slide 12 is disposed adjacent the upper portion of the outer face of the base of each gauge and normally the lower edge of the slide rests upon the flange 10. A transverse portion of the slide 12 has a depression or slot 13 which partially receives acircular nut 14 which is threaded upon the `screw projection 11. Obviously, by rotating the circular nut (the outer periphery of which is knurled to facilitate yits turning), the slide may be raised and lowered due to the screw projection being stationary and the nut engaging in the depression 13.

Threaded into the base adjacent its upper lOO portion'are screws 15, the Shanks of which pass through elongated slots 16 of the slide.

Plates 17 are secured upon the slide l2 and have slots ,L8 registering with the. slots in the slide.= The plates 17 rhave graduations 19 with which the pointers 20 cooperate for indicating the adjustment of the slide. `The pointers have their body v'portions guided in the slots 18. The body portions' orf the pointers have openings through which the shanks of the thumb screws pass. In fact, the bodies of the pointers engage between the body portions of the thumb screws and said plates. Afterthe slide is once adjusted, the screws which act to" guide `the slide l2 are tightened to insure holding the slide in'iposition. l

Y By Imeans of suitable holders 2l including clamping arms 22, spirit levels23 and l24 are mounted Yupon the slide. lThe spirit level 23 ris used Afor indicating whether or not the gauge is level in afdirection with the wallmwhilethe spirit level 24 is employed forfindicatin'gwhether or 'not the Wall is level in aldirection transversely thereof.

y yThe slide of eachgauge has a maisons line clamp 25.which .comprises the slide bar 26, 'the .,lateraljarm 27 jot' which engages the notch 2850i the edgeof theslide to hold the masonsl'ine or cord engaged with the-edge ofthe-slide. .The clamping V,slide of the line clamp is keyed between a plate 29 (which is secured to the slide) and one lface -of the slide, the securing meansof the plate lacting as guides for the opposite edge of the clamp- -ing slide. A suitable thumb screw 30 is threaded to the clamping slideand hasits shank `engaging through an elongated slot 3l`of said plate so as to hold the clamping slide in its clamping position. The masons l-ine or cord is engaged under the lat-eral arm of one'gauge and similarly connected tothe edge of the slide of the opposite gauge. The tworgauges are set, as shown in Figure l, Iand after the 'slides l2 are adjusted to their proper height to level the gauges ,longitudinally and transversely with the wall, the masons line will then be in a position to gauge the proper level of the bricks as they are laid. j The slide l2 of the gauge 'which includes the `base l has only one spirit level which indicates whether or not the wall .is level in a direction transversely thereof. The gauge which includes the base 2 has screws 32 threaded thereto which clamp a rulev gauge in. position on the base. The upper portion of theslide `l2 of one 'of the bricklayers gauges "is provided with screws 33 veither .one of which may clamp a rule gauge to the slide. Each rule gauge comprises long land short legs 34 and l35, the latter extending ,laterally to the former. The latter leg 35 is detachabledue to it including Ia slotted extension arm 3 6 which engages under v, the .head of the securing screw 37. Thelower rule gauge has its arm extending out Jfrom one end of the wall while the short arm of the upper rule' gaugeextends in a direction with and above the wall. Y i

The rule gauges each include a holder 38 having an opening orpassage therethrough 1for'the'recepti'on oi'ieither arm of the rule gauge, there being a set-screw 39 for securing the holder in different adjusted positions on the rule. VEach holder has an integral extension plate 41 which is slotted at 4() to receive a set-screw 42 by which the extension plate 411`na'y be secured in `any one of the depressions or countersinks.43a of theface plate 43, as shown -in Figures 7 and 9. rThese rule gauges are used iforgauging the laying of bricks in the construction of a. pilaster, as shown in Figures 7 and `8. In this application or' the rule gauges, the face plates lie against thebrick pilaster. However, the slotted exten/sion fplate 4l jmay engage with the shank oteither set-screw 33. In act,.the plate may engage between the head of the screw and one face of the slide l2, as in Figure I"lhefrulel gauge.I in this instance gauges the laying of the'bricks at the corner of a wall. lThe longand short arms of the rule gauges are graduated, preferably in inches, on their pposite'faces.

p Asi-shown in Figure 2,lrule .gauges including` holders-38 may. besecured tothe supporting or face plate v2by means of the screws 32 and 33. The screws 33 lare carried by the slide l2 while the screwsf32fare carried. by the plate 2. Inthis way, 'the holders 38 (which m-ay carry'the-long'leg rules .34) of *the 'rule' gauges are secured under the screws 33, hence are movable `with the slide l2. The holders 3S` of the 'rule gauges which are secured in place by'the screws 32 are carried by theipl'a'te 2.

It will be notedY that the .rules 34 have their longitudinal upper edges .iu'sh or level with the top edge of the plate 2 as'thisfgives the level line for layinga top layer ot`;bricks. It willalso be noted that thelholders 38 are constructed so as not toA protrude beyond one face of the plate 2, Ywhen used as yin Figure 2, or beyondjone face of thelface plate 43, so that when theplate 2 is usedas in Figure 2, it may lie fiat .against the wall and when the faceplate 43 is use-d in a similar manner 4to thatof the plate 2 in Fig- 'ure' 2, the "face plate 43 vvmay lie flat against the wall provided the rule 34 is removed.
